    MODEL DISCONTINUED AT FLIR ('Discontinued' on the manufacturer's page), but still actively sold by numerous professional distributors with no mention of its discontinued status, exactly like the already-covered TG267 in this catalog.

    Restricted distribution. At least one retailer states delivery limited to the United States, Canada, and Puerto Rico — a case of geographic restriction already seen with the Fluke Ti401 PRO and the FLIR ONE Edge Pro.

    Observations

    • The widest measurement range in the entire database at the high-temperature end. Up to 1030°C, thanks to a dedicated optical filter, versus 650°C for the best professional devices in this comparison. Designed for glass furnaces, industrial ovens, and forges — a use case entirely absent from the rest of the database.
    • Remarkable accuracy for a device in this segment. ±1.5°C between 50 and 100°C, versus generally ±2°C or more on the other imaging thermometers in the database.
    • A 30:1 distance-to-spot ratio, the best of the three FLIR TG models in the catalog (24:1 for the TG267 and the TG165-X).
    • Emissivity limited to four presets plus a custom setting, while most professional devices in this comparison offer continuous adjustment from 0.01 to 1.00.
    • Neither accuracy above 100°C, nor NETD conditions, nor a verified vertical field of view, nor full radiometry are documented.
